Classified as: Type 13 Lewis Acid/Base Complexation Chemistry
Many C-H bonds, which are usually polarised as Type 3 complexes (ie delta+ H), are often formed via Type 13 interactions in which a hydride ion reduces a Lobe-LUMO Lewis acid.
For more information look in the Chemogenesis webbook sections on Lewis acids and Lewis bases and the Lewis acid/base interaction matrix.HCHO |
